A hyperactive sunspot on the surface of the sun has fired off two of the most powerful solar flares of the year in just 24 hours, and promises to unleash more solar storms over the next several days, space weather experts say.

The active sunspot went into overdrive on Mother's Day when it erupted late Sunday night (May 12) with an X-class solar flare, the strongest type of solar storm possible, NASA scientists said in an update. That first eruption registered as an X1.7-class event on the space weather scale, and was followed midday Monday by an even more powerful X2.8 solar flare, which is the third-strongest solar storm in recent years.
